OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 484,030, dated October 11, 1892. Application filed March 9, 1891. Serial No. 384,263. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT Z. LIDDLE, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in Oil-Stoves, of which the following is a specification.

My invention relates to improvements in oil-stoves; and the object of my invention is to simplify the construction and to render the stove more efficient, safe, and durable. This object I attain by the construction illustrated in the accompanying drawings, which are herein referred to and forms part of this specification, and in which- Figure 1 isa perspective view of my stove. Fig. 2 is a transverse vertical section of the same, taken near the middle. Fig. 3 is a detached plan view of the perforated diaphragm and its frame. Fig. 4 is a detached plan View of the frame for holding the perforated diaphragm. Fig. 5 isadetached perspective View of the wick-tube of the form shown in Fig. 2, and Fig. 6 is an enlarged transverse vertical section of a modified form of the wick-tube, top plate, and binder, said top plate being shown broken widthwise.

As represented in the drawings, A designates the oil-reservoir of my stove, and B the top plate, which is secured to said reservoir by means of bolts in the usual manner of such construction. Said top plate is provided at its rearmost edge with grooved lugs 1, which form one part of the hinges for the chimney, and each of said lugs has a hook or arm 2, which projects laterally therefrom, said hooks projecting outwardly in opposite directions. At about the middle of its rearmost edge the top plate B is provided with a standing lug 3 of semi-tubular form and having a circular pit or depression 4 at the lower extremity of its concave side. Directly under the lug 3 the oil-reservoir A is provided with an upwardly-extending groove 5 in the lower part of its rearmost side, and said groove terminates at its inner end in an upwardlyextending circular pit 6. The top plate B isalso provided with a feedopening, which is covered by a detachable cap 7, which can be readily removed to allow the reservoir A to be filled with oil. I

O designates a detachable handle, which is preferably made of a stiff wire bent in the form, substantially as shown, to produce a downwardly-extended limb 8, that is fitted to engage in the lug 3' and pit 4, and a lower limb 9, that is fitted to engage in the groove 5, and is provided with an upwardly-turned end 10, that is fitted to engage in the pit 6. Said handle is preferably provided with an openly-formed spiral 11, made of small wire and attached to the larger wire of the handle 0 in such manner that afree circulation of air may be had between said spiral and larger wire for the purpose of keeping the handle 0 in a cool condition; but when preferred any material that is a non-conductor of heat may be substituted for the spiral 11. The

essential feature of the handle 0 is the mode of attaching it without bolts to the stove, so that it will be self-attaching and readily removable therefrom. The top plate B is provided with an oblong collar 12, which forms a slotted opening for receiving the Wick-tube. Said collar has a convexo-concave swell 13 at one side for the purpose of forming a recess let for containing a revoluble wick-raiser 15. At opposite ends of the collar 12 the lower side of the top plate B is provided with grooves which form the upper part of the journal-boxes for the shaft 16 of said Wick-raiser. One end of said shaft projects beyond the end of the swell 13, and it may, as shown in Fig. 1, extend beyond the end of the top plate B, and is provided witha milled head 17 or other appliance for rotating said wick-raiser.

D designates the wick-tube, which is made of sheet metal or other suitable material in the form of a flat tube, which fits snugly into the slotted openingin the collar 12. As shown in Figs. 2 and 5, said wick-tube is provided with lugs 18, which are integral with said tube and form bearings in which the wickraiser 15 is journaled. WVhen made in this form, said wick-tube is inserted in the slotted opening of the collar 12 by pushing itupwardly from the lower side of the top plate B, and it is secured in place by a binder 19, which bears upon the lugs 18 of said tube. As shown in Fig. 6, the wick-tube D is provided with transverse ribs 21, which are fitted to bear upon the upper face of the collar 12. In this last-described form said wicktube is inserted into the collar 12 from the upper face of the top plate 13. A lug or lugs 22 are formed at one side of said wick-tube, and being bent at right angles theretoare clamped between the top plate B and the binder 19. The latter in both forms of the wick-tube shown and described is secured to the under side of the top plate B either by means of screw-bolts 23, which pass through the wick tube D. Said diaphragm is usually made of perforated sheet metal and is held in a metallic frame 24, which is provided with feet 25,1h'a-t rest on the top plate B. Said frame is provided with lugs 26, which; are preferably formed at opposite ends of, said frame, with the upper face of same on} the same plane as the upper face of said: frame. At opposite sides of the opening in. said fra e longitudinal flanges 27 are formed 3 at sufficient distance below the plane of the lower side ofthe lugs 26 to permit the diaphrag-m E to be inserted in the space formed 5 bet-ween level of said lugs and flanges, said insertion being accomplished by first entering one end of it under one of the lugs 26, then bending said diaphragm upwardly until its,

free end will pass freely under the lug at the opposite end of the frame, and then pressing the diaphragm downward until the latter lies 3 smoothly in i ts place on the flanges 2 7. The

diaphragm E is provided with a slotted opening '28, through which the upper extremity of the wick-tube D will protrude.

F designates a chimney, which "consists of a base-piece 29, a tube 30, and a top frame Said basepiece is provided with arms -32, which extend rearwardly and downwardly therefrom, and each of which is provided with 4 a horizontal pintle 33. Said pintles range in the same line and extend toward each other,

so as to enter the grooves in the lugs 1 and form the complement of the hinge-joints for said chimney. Each of the arms 32 is provided with a projection 34, which by engaging with the rearmost side of the oil-reservoir A prevents the chimney F from being turned rearward beyond a required point. jections will also take against the hooks 2 when said chimney has attained an erect position, as shown in Fig. 1.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In an 0i1-stove,the combination of a perterated diaphragm made of flexible metal and a rigid metallic frame for said diphragm, provided at each of the inner sides of the opp-osite ends with inwardly-turned lugs and having at the inside of each of its opposite side bars a flange arranged at a lower plane than Said prosaid as and for the purpose herein speciv 2. In an oil-stove, the combination of a top plate provided with a collar having a slotted opening for containing a wick-tube and having a convexo concave swell formed at one side of said collar, a wicletub'e which fits into said slotted opening, and a binder secured to the lower side of said top plate and fitted to bear upon said wick-tuhe,as and for the purpose hereih specified.

'3. In anoil stove, the combination of a te'p plate provided with a collar having a slotted opening for containing a 'wick tube and having a GOHVQXO-GOHOQJVB swell at its side, the hollow of said swell forming part of a recess for containing a revolubl'e wick-raiser, and a slotted binder provided with a con vexo eoin cave swell at one side of its slotted opening, said swell forming the complement of the re cess for the wick-tube and said binder being secured to the icwer side of said top plate, so as to bear upon the wick-tube, as and for the purpose herein specified.
